G designates a shell shown as arranged'-v within the tube D. This shell. G is show as provided near ts lower end ith po or openings, as 9. These ports or openings 9' are shown as tapered in their sides and as being wider at their bottoms than at their tops. The upper end of the shell G is shown as provided with an inwardly and;

downwardly turned flange g.. and the space, formed by this flange g provides an an cushion, or air dash pot as G. The shell, (3*

and tube D may be held in position-l means of a screw, as 9 A shell, as H, is shown as arranged with in theshell G. Ports or openings/hare shown as provided in the lower end of this shell H, and the ports or openingsh are shown as tapered in their sides and as being wider at their tops than at their 'hottoins. A slot or groove. ash, may be provided in the side of the shell H and a projection, as,

9 on the interior of the shell G may fit into this slot or groove 7 preventing the rota tion of shell H and guiding the latter.

I designates a tube affixed to the shell The interior of this tube I is shown as tape ed. On the tube I a spider cap l is shown as arranged. is shown as depending a needle, as K, pro{ From this cap 5 therevided with asball or headlln which permits".

the. needle K to be held in a collarfas j,

shown as fastened to a screw threadedstud": 7, the upper end of which is showrras screwed into the cap J; 'A nut, as

shown as provided for locking the stud j in position, when set.

The stud j'f' be provided with a slot, as j into which a screw driver may be inserted to in'ovethe stud j, and, with it, thefneedle iga eme -or downward, as-desired.

L designates an inlet through which hydrocarbon may be introdueed'to a nozzle, as M, from a suitable tioat ehainberf N designates a horn which .acts as an air inlet. This hornlN is shown as provided with ports oropenings, as a, through which air may be a'dr'nitted tofthe hoi'n' It, and a valve,"a s"n', "isi'sliown as arranged in the horn N. 1 prefer that air introduced into the horn N be'heate but'iifJfor any reason, if r to the horifll he admitted through the describe "the j'opei tion 1 illustratin a carbureter einbodvin in?

improvement when the same is practically closed, and Fig. 2 illustrating the same carbureter when wide open.

At the outset it may be premised that when the carbureter is in a state of rest the ports 01*, g and hare not in communication, and that when the ports h are closed the smallest diameter of the tube I is on a line ,air confined in the space 0 the shell H will -move upward. The upward movement of the shell H carries upward the ports h, and

when the ports it have moved sufliciently far upward they are brought into communication with the ports 9 and mixed air and hydrocarbon passing through the ports h and g enters the chamber E through the portsor openings 03 The mixed air and hydrocarbon introduced into the chamber E finds outlet in the ports (Z and from the ports d passes into the neck B where it combines, with the mixture passing through cap J from tube I.- The valve 0 will, of course, cont-r01 the discharge from the B- y a .In the drawings I have shown a space, as Q, which may be loaded, as desired, to. in-- crease the Weight of the shell H.' .The upward movement of the shell Hwill necessarily cause an upward movement of the tube I, and the upward movement of the tube I will raise the needle K. The air cushion or air dash pot Ofwill, of course,

tend to check sudden movements of the shell H. It will of course be understood that in its movements: upward and downward the shell H is guided by the 'slotor groove h and projection 9 and that the tube D and shell G are held in proper position relatively .to each other by the screw 9 The lower reduced portion of the needle K is shown as cylindrical in shapei Thereby, while a risingmovement of the needle K opens the nozzle M yet, When.the lower tapered portion of the needle K has reachedthe level of the upper end of the nozzle M, further upward movement of the needle K does-not open the nozzle -M farther, but

when the lower tapered portion of the needle.

K has reached the upper end of the nozzle M the lower reduced cylindrical portion of the needle K acts as a guide for the needle K in further movement of said needle KQ I The shell H forms a 'carbureting chamber in which air and hydrocarbon are mixed and while the tendency of the mixed air and-hydrocarbon is to force itself upward through the tube I, yet, when the upward movement of the shell H- brings the'ports h and g into communication so that said ports form a passage between the, shell H and chamber E mixed air and hydrocarbon will flow from the shell H into the chamber E and this mixed air and hydrocarbon passes through the ports or openings (1 and mingles with the mixed air and hydrocarbon which has passed through the tube I.

What I claim as my invention and desire to secure by Letters Patentis:

In a carbureter, a casing, a tube therein spaced from the inner walls of the casing to form a chamber, said tube having ports communicatingswith the chamber, a shell within the tube having ports registering with certain of the ports of the tube, an inner shell movable vertically by suction'aga-inst an air cushion between portions of the side walls of the shells, and having ports registering at times with the ports of the first shell, means for introducing air into the chamber surrounding said tube and means for .introducing liquid fuel into the inner shell.

2. In a carbureter, a casing, 'a tube therein spaced from the inner walls of the casing to form a chamber, said tube having ports communicating with the chamber, a shell within the tube havingports registering with certain of the ports of the tube, a weighted inner she'll movable vertically by suction against an air cushion between portions of the side walls of the shells, and having ports registering at times with the ports of the first shell, means for introducing air into the chamber surrounding said tube, and means fol-introducing liquid fuel into the inner shell, said inner shell carrying a valve member projecting from the top thereof. p 3. In a carbureter, a casing,-a tube therein spaced from the inner walls of the casing to form a chamber, said tube having ports communicating with the chamber, a shell within the tube having ports registering with certain of the ports'of the tube, an. inner shell movable vertically by suction against an air cushion between portions-of the side walls of the shells, and having ports registering at times with the ports of the first shell, means for introducing air into the chamber surrounding said tube, means for introtapered valve member having a cylindrical lower portion, said" member being held within the socket, and means projecting through the cap for adjusting said member.,

4. In a carbureter, a casing, a tube therein spaced from the inner walls of the casing and having ports communicating with the upper and lower portions of thechamber.

thus formed, a shell within the tube having a flanged portion and having ports registerfirst shell, means for introducing air, means for introducing liquid fuel to the lower portion of the inner shell, the air and liquid fuel passing through the inner shell and com- 7 bining with the air passing through the registering ports and through the chamber be tween the casing and tube.
